The mining machine is supported on a truck or frame I, adapted to travel along a track A. This truck in the present instance has a pair of axles, with wheels 2 located thereon for supporting the truck on the track. 'I'he truck is driven by means of a motor 3. Suitably connected to one of the axles is a cable drum 4 upon which the electric cable for supplying current to the various motors may be wound. As the truck moves forwardly this drum will let off the cable, and as it moves backwardly this drum will take up the cable.

Located at the front end of the truck frame and immediately above the front axle are pedestals 5, which have a circular base 6 supported upon some suitable part of the frame. Extending downwardly from the base is an annular projection 'I, which fits in a suitable hole or opening therefor in the frame, 'provided in flanges I0. This `base is held upon the flanges, with the annular projection extending through the hole, by means of a plate 8 attached to the annular projection beneath the flanges by means of screws 9. The axis of rotation of the base and the pedestals passes through the axis of a cylindrical elevating frame pivotally supported between the pedestals.

On the periphery of the circular base are teeth I I engaged by a pinion I2 located on a shaft I3, suitably supported in the frame. This pinion I 2 is engaged by a pinion I4, which has integral therewith a worm gear I5. The worm gear I5 and the pinion I4 are rotatably mounted upon anaxle I6 supported by the frame, and a housing I1 which incloses the worm gear I5 and the pinion I4. The worm gear I5 is engaged by a worm located on a shaft I 8 of a motor I9.

The motor 3 for propelling the truck is provided with a shaft 20, which has thereon a worm 2I engaging a worm gear 22 mounted upon a vertical shaft 23u journalled in the frame, and a housing 24 supported on the frame. 'Ihis housing not only serves as a means for supporting one end of the shaft 23 but also incloses the worm gear 22 and the worm 2I. Y

'I'he shaft 23 also has thereon a bevel gear 26 which engages a bevel gear 26 mounted upon the rear axle 21 of the truck frame. Integral with the gear 26 is a gear 28, which engages a gear 29 located on one end of a longitudinally extending` shaft 30, which has on its other end a gear 3l meshing with a gear 32 upon the forward axle 21. Between the rear axle 21 and the drum 4 is a sprocket connection 21a. for `operating the drum.

In the upper end of each pedestal is a hole or bearing 33 concentric with teeth 35 arranged on the outer peripheries of flanges 34, one ange for each pedestal. Between the two pedestals there is pivotally supported a cylindrical elevating frame 36 by means of trimnions 31, one trunnion in each hole 33. To the rear end of this cylindrical elevating frame is attached a motor 38. These trunnions are in alignment with and directly above the front axle 21.

Around the front end of the cylindrical elevating frame is an annular housing 39, which has located therein a worm ring 40 engaged by a worm 4I upon a shaft 42 suitably journalled in the housing. On this shaft is also a bevel gear 43 which engages a bevel gear 44 located on one end of a 'shaft 45 of a motor 46. Located within the cylindrical elevating frame and within the worm ring is a y cylindrical rotating frame 41. The worm ring is splined to the cylindrical rotating frameby means of a spline 48. This spline permits the longitudinal movement of the rotating frame in regard to the Worm ring.

' Extending forwardly from the rotating frame are two brackets 49, each of which has therein a hole for receiving a. shaft 5I. On this shaft is a bevel gear 52 in mesh with a gear 53 on the front end of a shaft 54 journalled in a bearing 55 formed as part of the rotating frame. 'I'he rear end of the shaft 54 is connected to a shaft 51 by means of a coupling 56. These shafts 54 and 51 are driven by the motor 38, through a planetary gear mechanism later to be described.

Located on the under side of the elevating frame is a housing 58, which has therein a pinion 59 located on a transversely extending shaft 60. This shaft also has thereon a worm gear 6I engaged by a worm 62 located on a shaft 63 of a vmotor 64. The rotation of the motor will cause 40. In the present instance the Worm ring is operated by means of a. worm 69 located upon a shaft 10 journalled in a suitable housing.

This shaft 10 also has thereon a bevel gear 12 meshing with a bevel gear 13 on one end of. a shaft 14 of the motor 15. The worms 69, shaft 'I0 and gears 12 and 13 are located within a casing 1I. The operation of the motor 15 will cause the rotation of the rotating frame by means of the rotation of the worm ring 40.

On the front end of the rotating frame and supported thereon by means of the shaft 5I, is a double forked frame 16, shown in Figures 24 and 25. On the rearward part of this frame are two brackets 11, which have holes 18 therein to receive the shaft 5|. concentric with these holes and on the perlpheries of the brackets 11 are teeth 19 engaged by pinions 80 located on a shaft 8| journalled in the brackets 49.

On one end of the shaft 8| is a worm gear 82, which is engaged by a worm on the shaft 83 of a motor 84. 'Ihe operation of the motor 84 causes the pinions to rotate. These pinions, in engagement with the teeth 19 of the brackets 11, cause the double forked'frame 16 to rock on the shaft 5|, thereby elevating or lowering the front end of the double forked frame. This double forked frame is the rear frame of this same construction.

In this rear double forked frame there is supported a shaft in bearings 81. On the rear end of this shaft 05 is a bevel gear 86 engaged by a bevel gear 52a located upon the shaft 5|. On the forward end of the shaft 85 is a bevel gear 88.

On the double forked frame are forward brackets 89, which have therein holes adapted to align with holes 93 formed in rearwardly extending brackets 92 of a second double forked frame 9|. The rearwardly extending brackets 92 have thereon teeth 94 concentric with the holes 93. 'Ihrough the holes 90 and 93 extends a shaft 95, which has thereon a bevel gear 96 engaging the gear 88 on the front end of the shaft 85.

The teeth 94 on the brackets 92 are engaged by pinions 91 located on a shaft 98 journalled in bearings 99 in the frame 16. On this shaft is a worm gear |00 operated by means of a. motor |02 through a. connecting gear mechanism |0I. The rotation of the motor |02 operates the shaft 98 so that the frame is rotated on its pivot 95. Instead of having the motor |02 a motor |02a as shown in Figure 32 may be used.

On the motor shaft are two loosely mounted gears |02b and |02c adapted to be connected to the motor shaft by means of a clutch mechanism |02d. The gear |02b meshes with a gear |02e located on a shaft |02f. There is also fixed to this shaft a pinion |02g, which is smaller than the gear |02e. There is also on this shaft |023 a bevel gear |0|a which meshes with a bevel gear |0|b on a shaft |0|c for operating a worm for driving the worm gear |00.

|03 is a bearing located in the frame 9|, and it supports a shaft |04, which has on its rear end a gear |05 meshing with a gear 96a located on the shaft 95. On the front end of shaft |04 is a gear |06 for driving the shaft with its sprocket wheel thereon. The frame 9| has thereon a forwardly extending bracket |01, which has therein a hole |08 and teeth |09 arranged concentrically around the hole |08. Spaced from the bracket |01 is a second bracket ||0, which has therein a hole in alignment with the hole 08.

These brackets |01 and ||0 support the cutter head I2, which has extending rearwardly therefrom a pair of spaced arms ||3 which receive between them the bracket |01. These arms ||3 have aligned holes ||5. This head also has a rearwardly extending arm ||4 with a hole ||6 therein in alignment with the holes I5.

When the parts are assembled as shown in Figure 34 a sleeve ||1 extends through the holes |08 and ||5, and the sleeve ||8 passes through the holes and 6. By means of these two sleeves the cutter head is journalled upon the rear frame 9|. Extending through the sleeve ||1 is a shaft |9, which has on its lower end a bevel gear |28 which meshes with the gear |06 on the front end of the shaft |04. On the upper end of the shaft ||9 is av sprocket |2|.

' In the front end of the cutter head is a shaft |22 which has on the upper end thereof a pinion |23 adapted to engage with the teeth |09 on the bracket |01. On the lower end of. this shaft |22 is a worm gear |24 located within a housing |25. 'I'his worm gear is engaged by a worm |26 located on a shaft |21 of a motor |28.

Located upon the cutter head is a lug |29 adapted to receive on opposite sides parallel members |30 and |3|, connected by cross arms |32 to form the cutter bar. These cutter bar members have elongated holes |33 for receiving bolts |34, by which they may be attached adjustably to the cutter head. For the purpose of adjusting the cutter bar longitudinally with regard to the cutter head there is located in the lug a bolt |35 which passes through one of the cross arms |32 and has on each side of the cross arm an adjusting nut |36. One the front end of the cutter bar is a sprocket |31, which cooperates with the sprocket |2| for supporting the cutter chain |38, which has thereon a plurality of cutter teeth |39.

It will be noticed that the connection between each adjacent pivotally connected part has thereon a gear connected to a shaft for operating by a chain of gear and shaft mechanism, the sprocket chain by means of the motor located on the pedestals.

In Figure 15 there is shown a planetary gear connection between the motor 38 and the shaft 51. This gear mechanism is inclosed within a housing |40 attached to the front part of the motor and located within the rotating frame 41. Within the housing adjacent the motor is a partition |4I, which supports a bearing |42 for the shaft of the motor 38. 'Ihe end of the shaft is formed into a gear pinion |43, which meshes with a plurality of intermediate gears |44. In the present instance there are three of these gears, as shown in Figure 16, supported by means of a frame |45 which has suitable bearings for the intermeidate gears. Fixed within the housing |40 and around the intermediate gears is an internal gear |46 engaged by the intermediate gears.

'Ihe rotation of the motor shaft and the pinion |43 located thereon causes the intermediate gears to rotate. Since these gears engage the stationary internal gear |46 they will cause the frame in which they are journalled to rotate. Since this frame is directly connected to the shaft 51 it will rotate the shaft 51, and through it the shaft 54 and all of the gears operatively connected with the shaft 54, for operating the cutter chain located on the cutter bar. By this means there is provided a speed reduction between the motor shaft and the shaft 54.

For varying the relative difference between the speed of the motor shaft and the shaft 54 a motor |40a may be provided, which has on its shaft a worm |40b for engaging a cooperating worm gear formed on the periphery of the in ternal gear. This motor may be operated or not. The variation in the speed produced by the operation of this motor depends upon the direction in which it rotates. If the motor shaft rotates in one direction the speed may be increased, or if rotated in another direction the speed may be decreased. 'I'his motor is shown in Figures 19 and 20.

In Figures 36 and 37 a modified form of speed reduction is shown; In this form the motor is indicated by the numeral |41, and has attached thereto a-forwardly extending casing |48 which provides in its front end a bearing |49 for the shaft 51. The casing is attached to the motor frame by means of bolts Mila. At the point where the housing is attached to the motor there is provided a fixed clutch element |50, adapted to be engaged by a cap member which surrounds themotor shaft.

In the forward end of this cap member a disclike member |52 is threaded. This disc-like member has a forwardly extending sleeve |53 which closely fits around the shaft 5l but may be moved longitudinally of the shaft. Around the .shaft and within the casing Nilis a ring member |54, which has between it and the sleeve |53 a bearing |55. This bearing is held in place by means of rings |56, one threaded intofthe ring member |5ll and the other threaded on the sleeve |53 so that the bearings |55 are held fixed with relation to the sleeve |53. The sleeve and the ring |50 may move longitudinally of the shaft 51 and are urged in a lefthand direction by means of a spring |54a.

The cap member is rotatably mounted by means of bearings |51 on a projection |53 formed in the front part of the motor casing, and around the motor shaft |50. Fixed to the shaft itil, within the cap member |5|, is a clutch member |59. 'Ihe clutch member |59 and the clutch member |50 are fixed, one on the casing and the other on the motor shaft. The cap |5| cooperates with these clutch members and may be shifted on the projection |58 and on the shaft 5l.

Rotatably supported on the front end of the motor shaft |63 by means of bearings |52 is a frame |6l, which rotatably supports a plurality of pinions |53 supported in bearings |5| in the frame. These pinions, three in number in the present instance,.engage internally a ring gear |65 fixed to the cap |5|. The intermediate pinions |63 not only engage the teeth on the ring gear but also engage a pinion |5912 formed on the end of the motor shaft |55.

The rotation of the motor shaft will cause the pinions |63 to rotate. If the ring gear is stationary the frame |66 will rotate and carry with it the shaft 51, which is integrally formed therewith. Whenever the cap member |5| engages the clutch element |56 the ring gear is held stationary, and any rotation of the motor shaft will cause a less rapid rotation of the shaft 5l, but if the cap |5| were shifted so that it does not engage the clutch element |50 but does engage the clutch element |59, the cap will rotate with the motor shaft and cause the ring gear to rotate alsowith the motor shaft. 'I'here will be no rotation of the intermediate gears and the shaft 51 will rotate with the same speed as the motor shaft.

'Ihe cap |5| may be shifted by means of a lever |66, pivoted at the point |51. The lower end of this lever has thereon a yoke which engages the ring |54 for shifting the cap |5| longitudinally with respect to the motor shaft. To the upper end of the lever |66 one end of a link |68 is attached the other end of which link is attached to the upper end of a lever |69, pivoted at the point |10.

'Ihe lower end of the lever |69 is pivoted at the point 1| to a disc-like member |12, which has extending therefrom a core |13 projecting into the solenoid cylinder |14, around which there is wound a plurality of coils of wire |15,

Iadapted to conduct an electric current for causing the core H3 to move in or out of the cylinder |14.

In Figures 7c and '7b are shown the structures for tilting the elevating frame, consisting of a 5 motor 35a, suitably vlocated on the frame. This motor has a bevel gear 35h on the end of the motor shaft, which meshes with a bevel gear 35o on one end of a vertically extending shaft 35d, suitably supported on one side of the elevating frame. On the other end'of the shaft 35d is a worm 35e which meshes with a worm gear 35f, adjacent one end of a shaft 35g, which has on each end a pinion 35h engaging the teeth 35 on the anges 3|. By properly operating the motor 35a the elevating frame may be tilted in one direction or another.

In Figure l thelines a-b indicate positions in which the cutter-blade may operate for cutting various kerfs, either in a horizontal plane or in a `vertical. plane. Figure 2 shows various horizontal positions of the blade for cutting horizontal lrerfs. rIhis gure also shows the manner in which a semi-circular kerf may be cut above the truck or frame which supports the operating mechanism.

Figure 3 shows various kerfs that may be cut in a vertical plane. Figure l shows the various kerfs that maybe cut in a horizontal plane. In this figure the letters a--b-c show semi-circular kerfs on each side of the frame. The letters b--b-b show a semi-circular kerf that may be cut from one side of the frame, extending around and in front of the frame to the other side of the frame. A semi-circular line d-b-e shows the kerf that may be cut in a horizontal plane in front of the truck by rotating the cutter blade. Figure 5 shows various positions of the cutter operating in a plane transverse of the frame and extending in an arc across the frame, or to one side of the frame.-

In the various motors the speed may be controlled by the lever |55, similar to that shown in connection with Figure 36.

The extensible and articulate parts of the machine consist, flrst, of an elevating frame in which is located a cylindrical extensible frame, the latter rotating Within the former and extensible therein by means of a suitable motor. To the front end of the rotating frame is attached the rear end of a frame structure which has attached to its front end a similar frame structure.

These frame structures articulate with relation to each other and. also with relation to the rotating frame. To the front frame member is attached the cutter head so that it may rotate on an axis suitably provided therefor, either in a horizontal or any other plane, depending upon the position of the rotating frame within the elevating frame.

The pivotal connection between each of these elements, which consists of a shaft, has thereon gearing through which the cutting mechanism is operated by suitable shafts driven from the main motor and connected to these pivotal shafts by suitable gearing. By this means the cutting mechanism can be operated from the main motor regardless of its angular position with relation to the main motor.

It will be understood that I desire to comprehend within my invention such modifications as come within the scope of my claims and my invention.
